Name of the Vulnerable Software and Affected Versions Apache Traffic Control Traffic Ops (affected versions not specified)

Description The issue exists due to the lack of neutralization of special elements in the LDAP filter of Apache Traffic Control. An unauthenticated user can exploit this by sending a specially-crafted request to the POST /login endpoint of any API version, allowing them to inject unsanitized content into the LDAP filter and potentially execute arbitrary commands in the target system.

Recommendations As a temporary workaround, consider disabling the POST /login endpoint until a patch is available. Restrict access to the LDAP filter to minimize the risk of exploitation. Avoid using specially-crafted usernames in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
